MD97JB COMPASS SENS INT JUNCTION BOX

Features:
• Interfaces with Marine Data Fluxgate Coil Magnetic Sensors
• Generates Digital NMEA 0183 Heading Data from the Ship\u0092s Magnetic Compass or from the Marine Data MD53A Electromagnetic Compass
• Configurable for Earth\u0092s local magnetic variation and Ship\u0092s magnetic deviation with the Marine Data\u0099 MD93 Variation and Deviation Corrector
• Incorporates a Heading Stabilisation Filter
• Rugged, marinised aluminium alloy housing
• Independently tested to IEC60945:2002 by T\u00dcV Product Service Ltd.

Specifications:
Physical:
• Weight: 0.45kg
• Dimensions: 76mm overall width; 165mm overall length; 38mm overall height
• Mounting: Bulkhead mounted
• Connections (with options):
• 5 way socket for compass sensor (sensor available separately)
• 4 way socket for power and NMEA 0183 RS422 data output
• 7 way plug for direct connection with the Marine Data MD93 Variation and Deviation Corrector
• Option: 7 way socket for 2 x Furuno\u0099 compatible digital outputs
• Construction: Aluminium alloy enclosure
• Finish: Jet Black RAL9005; fine texture

Electrical:
• Power Supply: 24V DC nominal (18V-31V DC)
• Power Consumption (when connected to compass sensor): 1.5W without MD93; 3.5W with MD93

Data Input:
• MD52A Ship\u0092s Magnetic Compass Sensor (fluxgate coil); 10V, 400 500Hz
• MD53A Electromagnetic Compass (Earth\u0092s magnetic field sensor; fluxgate coil); 10V, 400 500Hz
• MD93 NMEA 0183 Variation and Deviation Corrector

Data Output:
• Digital RS422 NMEA 0183; 1 start bit; 8 data bits; no parity; 2 stop bits Baud rate: 4800 (other rates available as factory set options); heading data HDM, HDT & HDG (Variation and Deviation are output on data string HDG)

Operational:
• Performance with MD52A fitted: \u00b11.0\u00b0 accuracy with respect to the compass card. Overall performance is constrained by the vessel\u0092s magnetic compass operating in its binnacle
• Performance with MD53A fitted: \u00b11.0\u00b0 accuracy to Earth\u0092s magnetic field (in extreme case, \u00b13.0\u00b0)
• Update rate: 3Hz (other update rates available as factory options)
• Display: None. The required configuration accessory MD93 Variation and Deviation Corrector has an onboard 16 character alphanumeric LCD display which can show Magnetic Heading, True Heading (corrected magnetic heading) and Variation
